ABSTRACT:
A device for lifting and lowering visual displays, such as television sets, video monitors, plasma displays, pieces of art, or the like. The elevating device includes an elevating mechanism that elevates a first sliding frame and a second sliding frame. The first and second sliding frames move independently inside of a mounting frame. A motor rotates a pair of vertical threaded rods to drive the first sliding frame and cause the first sliding frame to rise and fall. A belt and pulley configuration transfers an elevating force from the first sliding frame to the second sliding frame. The second sliding frame includes supporting bars and is elevated to place the display at a desired height and is retracted to conceal the display in a cabinet, or the like.
